Title: In-mold coating powders with two initiators or 1,1-di (t-butylperoxy)-3,3,5-trimethylcyclochexane as a single initiator
Inventor: CUMMINGS FREDERICK L
IPC: C09D167/06

Abstract: ABSTRACT OF THE DISCLOSURE    Unsaturated polyester resin coaling powder composition consisting essentially of at least one unsaturated polyester resin; at least one copolymerizable second resin; and an initiator which comprises 1,1'-di(t-butylperoxy)-3,3,5-trimethylcyclo-hexane (AE) or which contains a small proportion of a fast initiator and a relatively large proportion of a slow initiator as defined herein.  Initiator AE has been found to work better as a single initiator than other initiators previously employed in in-mold powder coating formulations.  The combination of initiators works better than either one alone, and better than any of the few moderate rate initiators available.  A method is also disclosed for forming a cured unsaturated polyester surface coating on a cured unsaturated polyester substrate by coating one of the previously stated powder compositions on a heated mold surface so the coating flows and coalesces to form a partially crosslinked coating, then putting a charge of reinforced polyester resin in the mold and closing the mold, maintaining a suitable pressure and temperature for a time sufficient to cure the fill resin and the coating.  The coating and substrate are crosslinked across the interface between them when the part is cured.  Use of the present compositions in such a process has been found to provide improved surface characteristics of the coating.

Granted: 1994-05-10
Abstract: ABSTRACT OF THE DISCLOSURE         A power conversion system is disclosed in which a direct current is taken out of an AC power supply of variable frequency and variable voltage through a PWM converter in such a manner that in a region of low source voltage, the converter input current is limited to a predetermined value to maximize the DC power taking the voltage drop of the power supply into consideration with the power factor of "1" of the power supply, and when the current reaches an allowable maximum, it is limited to that value.  In a region of high source voltage, on the other hand, the quadrature component of the input voltage applied to the source voltage is controlled preferentially in a manner to control the converter input voltage below a predetermined value, thus making it possible to secure the maximum power available from the converter over the entire range of operation.  If a battery is connected to the DC side, a cooperative operation is made possible while the battery is charged properly.

Granted: 2003-01-14
Abstract: The present invention is directed to graft copolymers of nitrogenous monomers on polymeric methacrylate substrates and to their methods of preparation and use.   The graft copolymers of the invention are produced by preparing a mixture of constituent vinyl monomers suitable for being polymerized into a polymeric substrate, polymerizing a first portion of the mixture while adding a second portion of the mixture to the first portion to polymerize both the first and second portions to form the polymeric substrate. Thereafter, a nitrogenous monomer is grafted onto the polymeric substrate.     Hybrid copolymers of a nitrogenous graft copolymer with nitrogenous random polymers can be prepared by first forming the nitrogenous graft copolymer and then copolymerizing additional constituent vinyl monomers with the residual monomer to form the hybrid copolymer.

Granted: 1995-05-16
Abstract: An improved fastener assembly (10) for securing a rocker arm cover (11) to an engine block (13) is described. In the preferred embodiment, the fastener assembly is comprised of a bolt (15) with an unthreaded shaft (15b) between a head (15a) and a threaded end (15c) along a longitudinal axis of the bolt.  The bolt is in a slideable relationship within a cylindrical opening (19a) through a grommet (19) and a secured washer (17).  Projections or interference portions (15e) on the unthreaded shaft adjacent to the threaded section and opposite the head, restrict the axial movement of the bolt within the grommet and the washer.  While the rocker arm cover is being aligned on the engine block, the bolt is in an up position with the projecting surfaces adjacent to the washer.  Once the rocker arm cover is aligned, the bolt is threadingly mated with a threaded aperture (13a) in the engine block. The amount of torque that can be applied to the bolt is controlled by a shoulder (15g) of the unthreaded shaft section contacting the engine block.
